Abstract (en)
[origin: EP3089533A1] In order to change PUCCH transmission cells appropriately, the present invention provides a user terminal that communicates with a plurality of cell groups each consisting of one or more cells using different frequency bands, the user terminal comprising: a reception section that receives a radio resource control (RRC) message; and a control section that selects at least one cell from cells that are configured for each of the cell groups and are allocatable with an uplink control signal, and controls the cell to be a cell for transmitting the uplink control signal, wherein when the RRC message includes a change instruction of the cell allocatable with the uplink control signal, the control section controls to transmit transmission acknowledgement information (HARQ-ACK) in response to the RRC message in the cell before change.
